This beautiful heated Montana sapphire is a unique combination of two colors, pale blue and pale yellow. The yellow is more visible in person than the photo implies. The colors are in zones, creating a bicolored effect. The color was developed by heating the gem in Montana, but no other treatments were made to the gem. The treatment is permanent and stable and not only develops the color, but also improves the clarity. This sapphire has very slight inclusions that are just barely visible to the naked eye. The inclusions have been factored into the price, making this a great value for the size and color.
I faceted this sapphire in my custom “Hyperbola” brilliant oval design. The design is very bright and creates a beautiful pattern of scintillation in the hand. The gem weighs 2.15 carats and measures 8.1 x 6.9 x 5.1 mm; the perfect size for an engagement ring.
